METHOD AND APPARATUS FOR MANUFACTURING A COMBINED LIMESTONE AMENDMENT FOR AGRICULTURAL SOILS OF GRANITE MASSES.

摘要

P The plant has at least two storage, dosing and dispensing devices (1, 5), one of the limestone or dolomite component and the other of quicklime, which are connected to the inlet (21) a mixing mill (16) whose outlet (22) feeds a blowing and drying device. BR/ The invention is that the expansion device (27), in which the quicklime hydrating dries the limestone or dolomitic component, is housed in a chamber (30) confining the atmosphere so that the it heats up during the exothermic hydration of the quicklime and restores the heat also stored in said component to evaporate the wastewater it contains, this enclosure communicating (between 30 and 35) with the open air to evacuate the air saturated with water vapor and replace it with unsaturated air, and in that a third device for storing, dosing and dispensing (8) washing sludge and wet dust from the filtering is connected to the inlet (21) of the mixer (16). / P
